To all whom it may concern:

Be it known that I, Enron R. SEIFERT, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented a new and useful Improvement inBobbin-Winding Machines, of which the following is a specification.

This invention relates to a machine for winding small bobbins of cotton,linen or silk thread.

The object of the invention is to provide a compact machine which Willvery rapidly wind bobbins one after the other in an eilicient anddesirable manner, and as fast as one bobbin is completed automaticallypush it out of the way, commence the Winding of another bobbin, cut thethreadbetween two bobbins and discharge the completed and separatedbobbins from the machine.

The machine which is illustrated as embodying the invention has a needlewhich is rapidly rotated for Winding the thread thereon and which isstopped while the completed bobbin is being discharged; it has anoscillatory finger for guiding the thread and giving it a traverse Whilebeing wound upon the needle; it has a finger for pushing the bobbin whencompleted along the needle and shears for cutting the thread between twocompleted bobbins; it has a hook which temporarily catches the threadand so guides it that the last few windings will have no traverse butWill form a band about the middle of the completed bobbin, which hookalso temporarily guides the thread in such manner that the followingbobbin will be wound on the needle in the proper locality; it has afinger for disengaging thethread from the guiding hook: and there aremeans which when the bobbin is built up are actuated from the bobbin forcausing the proper action of the guiding hook, the discharging finger,the shears, the disengaging finger and for stopping the rotation of theneedle and then commencing the cycle again, all of these mechanismscoeperating to attain the automatic continuous production of tightlywound bobbins of thread.

Figure 1 of the accompanying drawings shows a plan View of the completemachine. Fig. 2 shows a front elevation of the same with one of thecasing plates removed. Fig. 3 shows a rear elevation with parts out invertical section on theplane indicated by the dotted line 3-8 on Fig. land looking in the direction indicated by the arrows. Fig. 4: shows avertical section on the plane indicated by the dotted line on Fig. 1looking in the direction indicated by the arrows. Fig. 5 shows a plan ofthe bed, with portions broken away, looking down on the plane indicatedby the dotted line 55 on Fig. 4:. Fig. 6 shows on larger-scale a plan ofthe oscillatory thread guiding finger. Fig. 7 shows a plan of the hookwhich temporarily engages the thread and causes the Winding of the bandand insures the starting of the winding of the bobbin at the properlocation on the Winding needle. Fig. 8 shows a plan of the dischargingfinger and its slide, and the shears and shear operating means. Fig. 9shows a front view of the discharge slide and shear opening finger. Fig.10 shows a face vicwof the shears. Fig. 11 is a detail'view showing thecam on the thread guide head for causing a clutch to release the windingneedle spindle from the rotatory shaft by which it is carried and drivenwhen the clutch is engaged. Fig. 12 is a face view lookinga-t the headwhich carries the oscillatory thread guide. Fig. 13 shows a full sizebobbin that has been Wound by one of these machines.

The bobbin 1 is wound onto the needle 2 which is angular in crosssection andthat projects from a rotatory spindle 3. The needle spindlepasses through a rotatory tubular shaft 4, anti-fricti0n bearings 5being arranged at each end between the spindle and the shaft. Movablymounted upon and keyed to the needle spindle near theend opposite theneedle is a male clutch member b and at the same end of the tubularshaft is a female clutch member 7, Fig. 4-. A pinion 8 is fastened onthe tubular shaft and meshing with this pinion is a gear 9 which Isfastened on the driving shaft 10 that is provided With a fixed pulley 11and loose forward over the needle. This finger is fastened to a block 14that is secured upon an arbor 15, Fig. 6, which is pivotally mounted inthe casing of the rotatable head 16. This arbor has two rocker arms 17that pivotally support a yoke 18, Fig. 3. Turning in the opening in thisyoke is an eccentric 19 that is secured to the end of a shaft 20 whichis journaled in the frame casing 21. Secured to this shaft near the endopposite from the eccentric is a gear 22 meshing with which is a gear 23on the driving shaft, 3. VYhen the machine is in operation these gearsthrough the eccentric, yoke and rocker arms cause the thread guidingfinger to rapidly oscillate.

On the drive shaft is a worm 24 engaging with which is a worm wheel 25that is loosely mounted on the cam shaft 26 which is supported inbearings in the bed 27 of the machine, Fig. 4. One side of the hub ofthe worm wheel has a clutch member 28 and sliding on the shaft isa'complementary clutch member 29 which is rotatably connected with acollar 30 that is fastened on .the shaft, Fig. 5. Springs 31 arearranged between the collar and the sliding clutch member in such manneras to tend to cause the engagement of the clutch parts. hen

. shaft and when the clutch members are disengaged the cam shaft remainsstationary. The cam shaft near the back of the machine carries a cam 32,Fig. 5. A lever 33 which is hung in the bed on an arbor 34 has a roll 35that is held in engagement with this cam. The front end of this lever isjoined to a vertically movable post 36, Fig.

4, and this post is connected by a link 37 with a crank arm 38 which isclamped upon a stud 39 projecting from the cap plate 40 on the end ofthe rotatablehead 16,

Fig. 12.

The head 16 is mounted to turn on a sleeve 41 which is secured to theframe casing 21,

anti-friction bearings 42 being interposed between the head and the endof the sleeve, Fig. 3. A spring 43 connected between the bed and thehead, Fig. 4, tends to turn the head over toward the front so that thethread guiding finger will normally travel .33 up with the roller-35against the cam 32.

When the cam shaft is clutched to the worm wheel and the machine isrunning the cam 32 is rotated so that at the proper time the 7 head isby, the connecting mechanism turned over'toward the back. This turningof the head lifts the. thread guiding finger a little distance above thewinding needle and it also causes the wedge cam 44 on the head,

Fig. 11, to engage the pin 45 and press it into engagement with a block46 on one end of a slide 47, the other end of which carries a clutchshifting arm 48, Fig. 1. The clutch shifting arm extends into a groove49 in the male clutch member 6 on the winding spindle. lVhen theshifting arm is pushed back by the action of the cam 44 on the guidecarrying head the male member 6 of the clutch is slid back against thethrust of the spring 50, Fig. 4, so as to disengage it from the femalemember 7 of the clutch and thus release the needle winding spindle fromthe tubular driving shaft, Fig. 4. When this occurs the winding needlestops rotating.

.VVhen the cam 32' allows the head to be returned toward the front thecam 44 permits the spring 50 to close the clutch so that the needle willresume winding.

The ejector finger 51 is secured to a hori- Zontally movable slide 52and it has an opening in its end through which the winding needlepasses, Fig. 8. This slide is mounted in the casing and has a projectinglug 53 that is held in engagement with the upper end of a lever 54 whichis mounted on a stud 55 and that has its lower end engaged with the cam56 on the cam shaft, Fig. 2. The ejector finger and slide are drawn backand the lever is held against the cam by the pull of the spring 57. Atthe proper time the cam 56 moves the ejector finger out so as to push awound bobbin along the winding needle from winding position.

The wedge shaped shearopening finger 58 is carried by the ejector fingerand when the ejector is moved out the shear opening finger is pushedbetween the shanks 59 of the shear blades 60, Fig. 9. The lower shearblade is fixed upon a stud 61 held in the bracket 62 mounted on theframe casing, while the upper shear blade is pivotally mounted on. thisstud. The shear blades are held normally closed by a spring 63, Fig. 10,and are opened by the passage between their shanks of the wedge shapedfinger 58. The cam which actuates the ejector and shear slide is of suchshape that the ejector and the shear opening finger are moved outwardcomparatively slow, but are allowed to be drawn back by the spring veryrapidly so that the ejector will get out of the way and the shear bladeswill close quickly for severing the thread between two wound bob bins.

The chute 64 into which the bobbins are discharged from the windingneedle, is fastened at its upper end to the bracket 62 to which theshear blades are pivoted, Fig. 4.

As the bobbin is about completed a few threads are wound about themiddle and when the completed bobbin is pushed along the winding needleby the ejector finger the thread leading from the oscillatory threadpurpose a hook is adjustably secured to a finger 66 that "is adjustablyattached to a slide 67, Fig. 7. This slide is mounted in the casing andhas a lug 68 which is engaged by the upper end of a lever 69 that ispivoted in the case on the stud 55, Fig. 2. Thelower end of" this leveris held engaged with the cam 70 on the cam shaft by the pull of thespring 71 which is connected between the slide and the casing. This camis so formed that at the proper time the guiding hook is allowed to moveout and catch the thread between the bobbin and the oscillatory threadguide and temporarily retain it so that the last few windings of thethread will not have a traverse, but will wind a band abou'tthe middleof the bobbin, Fig. 13, and the hook also retains the thread so that the'neXt bobbin will be started right.

In order to release the thread from the hook after the winding of thebobbin has commenced a finger 72 is hinged to the outside of the casingof the head 16, Fig. 1, in su'chmanner that when the head is turned overtoward the back the tip of this finger will be drawn away from the hook.When the head is again turned forward the tip of the finger'i's slidover the hook and pushes 'the thread therefrom, Fig. 12.

Below the locality on the needle where the bobbin is wound is a button73. This "button is clamped to the upper end of a verftic'ally movableslide 74. The lower end of this slide 'is engaged by one end of a rockerlever 75 which is pivoted in the bed. The otlier end of the rocker leveris connected by a link 76 with the lower end of a lever 77 thatispivoted on the arbor 34. The upper end of the lever 77 is engaged witha pin '78 which is pressed by a spring 79 toward the movable member 29of the clutch 1 on the cam shaft, Fig. if

On the movable clutch member is a wedge 80, Fig. 5. When this wedgeengages the pin 7 8 the movable member is pushed forward and the membersof the clutch are disnecting levers and link withdraws the pin therebywill be rotated so as to perform their functions. The cams are so timedthat when the button is pushed down by the bobbin the hook catches andholds the thread sothat the last few turns will be wound withouttraverse. Then the spindle is stopped, the completed bobbin is pushed bythe ejector along the needle and the shears are opened. WVhen theejector returns the shears close and cut the thread between the bobbinjust pushed by the ejector and a bobbin that was previously formed andwhich in the machine illustrated remains on the needle until thefollowing bobbin is formed, allowing that previously formed bobbin todrop into the chute and pass from the machine. The needle then resumeswinding and the thread is disengaged from the hook. The winding thencontinues until another bobbin is formed when the cycle of operationsdescribed is repeated.
